Detailed DescriptionNoise model for photon and sensor read noise, assuming that they are independent random variables and spatially invariant.The noise model is N (x) = sqrt (scale*x + offset), where x represents a linear signal value in the range [0,1], and N (x) is the standard deviation (i.e., noise). The parameters scale and offset are both sensor-dependent and ISO-dependent. scale must be positive, and offset must be non-negative. Member Function Documentation
Return the mapping for value x. This method must be implemented by a derived class of dng_1d_function and the derived class determines the lookup method and function used.
Implements dng_1d_function.
